which may be folded into a relatively small bundle for convenient handling in transit and storage, thereby adapting it for use by tourists and campers in thatit may be conveniently packed away in a comparatively small space when traveling' from'place to place.

The particular object of the invention 1s to provide an improved folding bed havlng the frame members so hinged vand pivoted together that when the bed is folded, the frame members will be in substantially parallel abutting relation, thereby providing such a structure which may be folded into a very small and compact bundle. i

Other objects of the invention will Vappear from the following description and the accompanying drawings and will be pointed out in the annexed claims.

In the accompanying drawi'ngs there has been disclosed a structure vdesigned to carry out the various objects of the invention but it is to be understood that the invention is not confined to the eXact features shown as various changes may be made within the scope of the claims which follow.

In the accompanying drawings formlng part of this specification:

Figure 6 is a similar view showlng the legs in folded position; and

Figure 7 is a detail view showing the novel construction of the joints provided in the side rail sections.

The novel folding bed featured in this invention preferably comprises the opposed.

end rails 11 having the side rail sections 12 and 13 pivotally connected thereto as particularly shown in Figures 2, 3 and 4:. The side rail sections 12 are pivotally connected to the end rails 11 by means of suitable studs orv rivets 14: as shown in Figures 2, 5 and 6. The inner Corners of the rail sections 12 are preferably rounded asshown at 15 so that they may be foldedtinto the' end rails 11 as shown in Figures 3 and 4.

A -feature of the invention resides in the novel constructionof thepivotal connection between the side rail sections 13 and the end rails 11. These connections are so constructed that when the bed is folded, the rail sections 13 will be spaced from the end rails 11, as particularly shown in Figure 4, thereby providng suitable clearance for the rail sections 12 which will be interposed between the rail sections 13 and the end rails 11 when the frame is infolded position as shownin Figure 4. Referring to this figure, it will be noted that the side rail sections 13 each have a bracket 16 secured thereto which brackets have their opposite end's pivotally connected to the end rails 11 by pivot pins 17 located a short distanc'e from the ends of the rails las shown particularly in Figure 2. The pins 17 are located in the end rails 11 as above clescribed so that when the bed is in folded position as shown in Figur-e 1, the outer faces of the rail sections 13 will be in alineinent with the ends of the end rails 11, thereby providing a rectangular frame.- The primary object of the brackets 16' is to provide means for offsetting the rail sections 13 from 'the end rails 11 when the frame is completely folded for the purpose of providing clearance for the rail sections 12 which7 as before mentioned, will be interposed between the end rails 11 and the rail sections 13 when the structure is in the position shown in Figure 4. f r i Another feature of the invention resides in the novel. construction of the pivotal connection between the side rail sections12 and 13. i Referring to Figure 7, it will be noted that the rail sections 12 and 13 are preferablyl constructed of angle bars and the rail sections 12 are preferably fitted over the sections 13. A shouldered stud 18 is secured to each rail section 12 to enter elongated opening's or` slots 19 provided in the adjacent end-portions of the rail sections 13 as shown. A shouldered lstud 21-'is also mounted inthe Vertical' web of each rail section 13 tol enter bayonet slots 22 terminally provided in the adjacent end-portions of the rail sections 12. By this novel construction, it will be noted that the rail sections are also adapted for a longitudinal or slidable movement to provide for securely looking the Sections together 'when the bed is in unfolded position as shown in Figure 1.

In the operation of this novel hinge `construction the pivot pins 21, when the bed is in unfolded position, will be seated in the recesses 23 of the sockets 22, thereby preventing the rail Sections from aceidentally pulling apart or bec-oming unlocked so that they maybe folded as shown in Figures 2 and 3. Vhen it is desired to fold the bed, a slight upward movement is imparted to the pivot-al connection of the rail Sections 12 and 13 which will cause the pivot pins 21 to be moved downwardly `out of the recesses 23 in the rail sections 12, after which the Sections may be pulled apart as shown in Figure 7. VVhen the pivot pins 21 mounted in the seetions 13 have thus been removed from the b-ayonet slots 22, the two sections on each side of the bed may readily be folded as shown in Figures 2 and 3. When the bed is erected, as shown in Figurc 1, and the pivot pin 21 are again seated in the recesses 23, of the slots 22, the side rail sections will be securely held together substantially as a one-piece structure, thereby providing a very substantial pivo't-al connection between the rail Sections so that such connections cannot accidentally become unloc-ked from each other.

The arrangement of the end irons with their concave faces'directed inwardly and downwardly, and with the side rails pivoted beneath the end rails, disposes the upper portions of the Vertical flanges of the end rails as abutments for the end faces of the side rails, to 'receive the thrust caused by the tension of the spring fabric 24.

The extensions 16 are principa-lly for the purpose of permitting nesting vin the manner shown in Figure 4, wherein it will be seen that the arm 16 acts to dispose the rails 13 outwardly so that all members of the device can assume a strictly parallel relation when nested. V

Another feature of this invention resides in the .novel method of pivotally connecting` the supporting legs 24 to the end .rails `11. Referring to Figure 5, it will be noted that each leg 24 is also constructed of angle bar and that the upper portion of one of the webs thereof is cut away to provide a lug vor, extension 25 which is pivotally connected to the'end rail 11 by means of a pin 26. ShitableV braces 27 are pivotally connectedv to the leg and'have their upper ends adapted to-'be demountably connected to the pins 28 and 29 in the end rail 11 and rail section 12, respectively, as shown. When the leg is in unfolded position as shown in Figure 5, the diagonalrbraces 27 are secured to the pins 28 and 29, thereby securely b-racing the leg in unfolded position. A feature of the construction above described resides in the particular location of the pivot pin 26 in the end rail 11, which preferably is such as to cause the upper end 31 of the relatively shorter web of the leg to abut against the lower edge 32 of the side rail section 12, when the leg is in unfolded position. By this novel arrangement, it will readily be understood that when the bed is set up, as shown in Figure 1, the weight of the rail sections 12 and 13 and the load carried thereby will not be carried entirely by the pivot pins 26, but rather upon the upper ends of the legs .24 as a result of the lower ed ges 32 of the rail Sections 12 and 13 bearing); directly against the upper ends 31 of the .legs as clearly shown in Figure. When it is desired to fold the bed to the position shown in` Figure 4, the diagonal braces 27 will be disconnected from the headed pins 28 land 29V after which the legs may readilybe folded against the end rails 11 as shown in Figure 6. .w

.An `offset plate 33, having a plurality of spaced apertures 34, is suitably secured to each end rail 11 to provide means for securing` thereto and usual fabric eovering 34 shown in Figure 1. This covering may be of any suitable material applicable for the purpose, and as it forms no part of the present invention, it is thought unnecessary to show same in detail..

In the operation of folding this novel bed the legs 24are first folded to the position shown in Figure 6, and the rectangular bed frame placed upon the floor. The pivotal connections in the side rail Sections 12 and 13 are then unlocked by slightly raising each joint soas to cause the rail Sections 13 to be downwardly moved to the dotted line position shown in Figure 7, after which the pins 21 may be moved o-ut of the recesses 23 and the rail Sections pulled apart as shown in this figure. The rail sectionsi12 and 13 are then inwardly folded as shown in` Figure 2, the railsections 12 following the paths indicated b the dotted lines and arrows in Figure 2. Von'tinued inward movement of the rail sections will cause the end rails 11 to be inwardly drawn to the position shown in Figure 3 after which .the entire bed may be folded into the .position shown in 'Figure 4, wherein it will benoted that the rail Sections end rails, and the legs 24 lwill be substantia ly in parallel relation and in such a manner that the folded bed as a whole may be stored or packed away in a relatively small space.

This novel structure is also preferably constructed of angle iron ba-rs thereby providing a folding bed which, when in unfolded position as shown in Figure 1, will providea very rugged and substantial bed capable of carrying a considerable,weight without danger of collapsing. Also as a result of the means provided for lockingthe pivotal connections of the rail Sections 12 and 13 in unfolded position, the bed as a whole, may readily be moved about upon the floor without danger of accidentally collapsing or folding together.
